Title: Means Generating an Output Signal as a Predetermined Function of a Variable Input Signal
Inventor: BANKS CECIL HENRY
IPC: G06F3/00
Filed: 1966-12-16
Abstract: 1,170,068. Logarithmic function generators. WITTON ELECTRONICS Ltd. 15 Dec., 1967 [16 Dec., 1966], No. 56402/66. Heading G4G A logarithmic or similar high order function generator comprises a cathode-ray tube with stabilized gun voltage wherein the screen is partially covered with an opaque skew - symmetric mask M defining the required function; the emergent light being focused on a photo-cell P and amplified to vertically deflect the spot, whereby the latter is maintained on the mask edge. An input voltage energizes variable gain amplifier G to horizontally deflect the spot, and the gain is varied inversely with the vertical deflection voltage in opposition to a variable bias voltage B so that at zero input the spot lies at the centre of symmetry of the mask curve and is deflected in series corresponding to the input. The vertical deflection voltage then represents the required function voltage. The variable gain amplifier may comprise cascaded Hall multiplers magnetized by transistorized amplifiers inversely to the control signal, having an inverse square law. The output signal may feed a linear recorder printing out the result on logarithmically graduated paper, and the device is applicable to the measurement of rapidly variable electrochemical phenomena.

Title: Improvements in or relating to Ball-and-Socket Joints
IPC: F16C33/14
Filed: 1967-12-13
Abstract: 1,150,048. Ball and socket joints. SKF KUGELLAGERFABRIKEN G.m.b.H. 13 Dec., 1967 [14 Dec., 1966], No. 56691/67. Heading E2F. A ball and socket joint has a plastic insert 6 separated into two parts by a central flange 5 disposed in the bore of an outer ring and pointing radially inwards. The inside diameter of the central flange is only slightly greater than the outside diameter of the spherical inner ring 1, so that the inner ring is a sliding fit in the central flange. The outer ring 3 may have a recess 8 on the surface so that the central flange can yield resiliently. In other embodiments, an end flange may be bent upwards to allow insertion of the inner ring (Fig. 2, not shown) before being bent back; or the outer ring may have an opening on one side for the inner ring (Fig. 3, not shown); or a ring of circular cross section may be inserted in the bore of the outer ring instead of an integral side flange (Fig. 4, not shown).

Title: Device for cutting continuous-feed material
IPC: A61F13/15
Filed: 1973-12-07
Abstract: 1448568 Cutting apparatus S G BRYNGEL. SON 7 Dec 1973 [8 Dec 1972] 56887/73 Heading B4B A device for cutting continuous feed material 3, e.g. in strip or tape form, into predetermined lengths comprises a cutting member 4 mounted on a carrier means 1, the cutting member being reciprocated by a cam member 5 between a cutting position and an inoperative position relative to a surface of the carrier on which the material is carried. The cutting member 4 is pivotally-mounted within a slot 6 formed in the periphery of a wheel constituting the carrier 1. The cutting member is formed with an arm 13 which is adapted to be engaged by a spring 7. Upon rotation of the carrier the spring is deflected by the cam 5 to move the cutting member into its cutting position. After a certain rotation of the carrier, the spring suddenly moves out of contact with the spring, thereby allowing the latter to engage a further arm 15 on the cutting member and so causing it to snap into the slot 6 to cut the material. The material is drawn on to the surface of the carrier by suction applied to holes 8, Fig. 2. The speed of rotation of the carrier 1 is greater than that of supply reel 9 thereby causing slippage of the material on the surface of the carrier. By adjusting the relative speeds, different lengths of material may be cut. The cutting device may be incorporated in a machine applying adhesive tape to sanitary napkins, Fig. 1 (not shown).

Title: A Circuit for Energizing a Load
IPC: H03K3/037
Filed: 1967-12-19
Abstract: 1,173,459. Switching systems for consuming apparatus. E. W. BLISS CO. 19 Dec., 1967 [29 Dec., 1966], No. 57512/67. Heading H2H. A circuit arrangement for ensuring that the supply to a load L is switched on at the beginning of a cycle of the A.C. supply 2 comprises a capacitor C chargeable from a D.C. source B, the capacitor C being shunted by two circuits, one including a randomly actuatable switch S and the other a switching device such as a transistor 10 rendered alternately conducting and non-conducting at a frequency corresponding to that of the A.C. supply 2, a signal from the capacitor C being supplied to a bi-stable multivibrator M to switch on the supply to the load L, the duration of which supply is determined by a timing device T energized simultaneously with the load. With the switch S in its normally closed position, the capacitor C remains in its discharged state, but when the switch is opened by random operation thereof the capacitor charges and discharges in accordance with the non-conductive and conductive states of the transistor 10, that is, during the positive and negative half-cycles respectively of the A.C. supply V. During a positive halfcycle when the capacitor is charging, the signal applied to the multivibrator M-which comprises a pair of NOR circuits 32, 34-is such that the multivibrator has no output and the load L remains unenergized. At the beginning of the following negative, the capacitor begins to discharge and the signal applied to the multivibrator is now such that it has an output whereby the load L is energized. The timing device T is energized simultaneously so as to maintain the output of the multivibrator until the end of the period determined by the device, whereafter the multivibrator returns to the state in which it has no output. Thus, irrespective of the moment of operation of the switch S, the load L is always energized at the beginning of a negative half-cycle of the supply V for a period determined by the timing device T.
